Abstract: 1,197,908. Power-assisted steering. CAM GEARS Ltd. 18 July, 1968 [30 June, 1967], No. 30217/67. Heading B7H. The valve means in a power-assisted steering or like gear with a double-acting hydraulic servomotor 12, comprises four poppet valves 4, 5, 6 and 7 which are movable towards and away from their seats in accordance with the torsional strain in a torque-transmitting resilient element 2 to control the flow of working fluid to and from the servomotor. In the neutral position the valves may all he closed (Fig. 1) or partially open (Fig. 3, not shown) or two may be closed and two partially open (Fig. 2, not shown). As shown diagrammatically in Fig. 1 the driver operable element 2 comprises a pinion 8 engaging a rack 9 and a flat member 3 rotation of which, relative to the rotatable valve sleeve 15 in which are mounted the poppet valves, opens two opposite poppet valves and closes or moves away from the other pair of valves. The chambers above the heads of the valves 5, 6 are connected to a fluid pump 19 and the chambers above the heads of the valves 4, 7 to both a respective end of the servomotor and, by a duct 22 or 23, to the chamber below the head of the adjacent valve 6 or 5. The chambers below the heads of the valves 4, 7 communicate with a reservoir 17. On rotation of the member 3 in the direction of the arrow 1 relative to the sleeve 15 for example, the valves 6 and 7 are opened permitting pressure fluid to pass through the conduit 20, valve 6 and duct 22, and above the closed valve 4 to the left-hand end of the servomotor 12 and fluid is exhausted from the right-hand end of the servomotor 12 through the valve 7 to the reservoir 17. In an alternative construction, Fig. 4, the flat member 50 is part of the steering input shaft 49 and encloses a torsion bar 52 which interconnects the shaft 49 and a pinion shaft 46 rotationally secured by a pin 46A to a sleeve member 53 having three annular chambers 55, 56, 57 in which are disposed one, two and one poppet valve respectively. Each chamber e.g. 55 with a single poppet valve 60, also includes a fluid pressure balancing plunger 60E. The valve neutral position is adjustable by rotation of a screw 65 with an eccentric head 64 which engages a groove 63 in the sleeve 53 thereby moving the sleeve and poppet valves axially of the member 50 the " feathers " 51A of which have a slight helical twist. The poppet valves may comprise balls unseatable by short push rods and the invention may be used with other, such as worm and sector, steering gear and other, such as vane-type, servomotors.

Title: A process for the production of organic acetates
Inventor: KROENIG WALTER
IPC: B01J23/58
Filed: 1965-07-16
Abstract: Organic acetates are prepared by reacting an olefine or alkyl benzene with oxygen and acetic acid in the presence of a palladium metal catalyst supported upon aluminium spinel which may contain aluminium oxide.  Ethylene, propylene and iso-butylene, and toluene and xylene are mentioned and the support may be impregnated with palladium salt followed by reduction with hydrazine hydrate or hydrogen at high temperatures.  Alkali or alkaline earth metal acetates, e.g. sodium, potassium, magnesium or calcium, may also be present.  The spinel support is prepared from metals such as lithium, beryllium, magnesium, zinc, and bivalent manganese, iron, cobalt and nickel. Examples describe the preparation of vinyl acetate, allyl acetate, benzyl acetate and benzal diacetate.ALSO:Palladium metal catalysts deposited on a support consisting partly or completely of aluminium spinel which may contain aluminium oxide, are used in the preparation of organic acetates by reacting an olefine or alkyl benzene at elevated temperature with oxygen and acetic acid.  The catalyst support is prepared by adding the spinel-forming metals e.g. lithium, beryllium, magnesium, zinc and in the bivalent form, manganese, iron cobalt and nickel, as salts or hydroxides to the aluminium oxide, drying, converting to oxide at from 250-650 DEG C, and finally heating at 900 to 1200 DEG C to form the spinel.  The aluminium oxide may be in piece form, or fine-grained and in a modification metal aluminates may be precipitated from aqueous aluminium salt solutions by adding salts of spinel forming metals and heat treating the product.  In a further method the aluminium oxide or hydroxide is mixed with spinel-forming metal oxides or hydroxides, ground, shaped and heated to form the spinels.  The palladium is deposited e.g. 0.1 to 10.1 by weight by impregnation with a salt solution followed by reduction with hydrozine hydrate, or hydrogen.  Alkali or alkaline earth metal acetates e.g. potassium, sodium magnesium or calcium may also be included and the process may use fixed or moving bed catalyses.

Filed: 1974-07-10
Abstract: 1475344 Separation of phosphor particles by flotation RCA CORPORATION 10 July 1974 [20 July 1973] 30593/74 Heading B2H [Also in Division C4] Oxidisable metal sulphide phosphor particles are separted from a mixture with non-oxidisable phosphor particles by forming an aqueous slurry containing the mixture, a mineral acid and an alkali nitrite. The metal sulphide phosphor particles are oxidised and rise and float on the surface under the influence of the gases produced by the reaction and may be removed therefrom by skimming or decantation. The non-oxidisable phosphor particles settle on the bottom. In one example an alkaline sludge produced from washing out television picture tubes and containing red-emitting europiumactivated yttrium oxysulphide, green-emitting copper- and aluminium-activated zinc-cadmium sulphide and blue-emitting silver activated zinc sulphide phosphor together with organic binders and aluminates is first digested with a hydrogen peroxide solution and is then acidified, washed dried and baked in air to remove organic material. The mixed phosphor powder is then formed into a slurry and treated with sulphuric acid and sodium nitrite whereby the green- and blue-emitting phosphor particles are oxidised and float on the surface, whereas the red-emitting phosphor particles settle on the bottom of the vessel. Another example describes the separation of red-emitting yttrium vanadate phosphor particles from a mixture containing blue- and green-emitting prosphors and aluminium metal particles in which the aluminium particles are first dissolved in an alkali hydroxide solution.

Abstract: 966,331. Bakery apparatus; batching conveyers. BAKER PERKINS Ltd. Aug. 21, 1962 [Aug. 24, 1961], No. 30595/61. Heading A2A. [Also in Division B8] In a machine for spacing equidistant conveyer borne articles, e.g. biscuits, into batches, the biscuits are received on to a first endless belt 2 at 12 and are transferred over a reciprocated gap or zone 4 on to a second, faster-moving, endless belt 3. The transfer zone is moved forward, i.e. from position 10 to position 11, at a speed intermediate the speeds of the conveyers 2, 3 and then back again at a substantially slower speed. During this backward motion biscuits are transferred from conveyer 2 to the faster conveyer 3 and these become spaced ahead of biscuits left behind on the conveyer 2 when the zone 4 moves forward again. Reciprocation of the zone 4 is effected by varying the lengths of bights C, D in the conveyer bands 2, 3 and for this purpose turning point rolls 5, 7 at the zone 4 and bight rolls 6, 8 of the conveyers are mounted on a reciprocated carriage 9 driven by a pair of oscillating levers 22 mounted on a shaft 22b, which in turn is oscillated by a rotary cam 24 and follower 25 connected by an adjustable length link 26 and stub lever 22a to shaft 22b externally of the machine framework 32. The cam 24 is chain driven from a motor 31 and chains from the shaft of the cam 24 operate the drive rolls 15, 18 of the conveyers 2, 3. The device is particularly suitable for use in conjunction with a batch gap maintaining device as described in Specification 966,332 to supply batches of biscuits to the plaques of a tier type cooling device.

Title: Apparatus for recording patterns of electromagnetic radiation
IPC: G01T1/164
Filed: 1970-06-24
Abstract: 1313098 Scintillation camera PICKER CORP 24 June 1970 [27 June 1969] 30691/70 Heading H4F In a scintillation camera in which the output signals from an array of photo-tubes, arranged to detect light flashes produced by a scintillation crystal in response to incident gamma radiation, are selectively combined (decoded) to produce analogue signals representative of the intensity Z and co-ordinates X, Y of the successive light flashes, the co-ordinate signals are converted into digital signals, serially recorded along a record strip, e.g. a magnetic tape for subsequent playback, and reconverted back into analogue signals for display, e.g., on a C.R.T. which may be photographed. The intensity Z and co-ordinate X and Y signals corresponding to each light flash are supplied via an analogue computer to the A/D converter, which computer includes a pulse height analyser so that only co-ordinate signals corresponding to a selected intensity are recorded and displayed. If it is desired to record signals corresponding to two (or more) different intensities (i.e. different radiation energy levels, e.g. radiation emitted by two isotopes) then the photo-tube output signals are supplied to two (or more) analogue computers each including a pulse height analyser. The resulting co-ordinate signals corresponding to different radiation levels are passed to the A/D converter and then stored together with flag signals from the pulse height analysers that indicate from which of the two (or more) channels (analogue computers) the signals being stored are received. If there is only two channels only one flag signal instead of two diffetent flag signals need be generated to identify the signals. In response to a selector switch the X and Y signals may be attenuated by a factor of 2 and signals corresponding to each energy level displayed on separate areas of the display C.R.T. according to the associated flag signals, alternatively all the signals may be displayed to produce a single composite visual display on the C.R.T. screen, or the signals from only one of the channels may be displayed. Calibration of the individual photo-tubes of the scintillation camera may be effected to compensate for variations in gain of any of the photo-tubes or preamplifiers. This calibration is effected using a selector switch which enables any photo-tube output to be selected and fed via a test switch and a multiplexer to a data processor, e.g. an oscilloscope on which a variable-width profile histogram of counts versus horizontal distance or a histogram of counts versus time may be displayed. The display may include a smoothing generator that causes the dots to flow together and present a more continuous pattern. In addition the orientation of the displayed pattern may be rotated. The devices for effecting the analogue to digital conversion and recording of the signals may be switched out of circuit when it is desired to produce a scintillation display quickly.
